Exclusive: Ferocious Photos From the Protester Side of Ukraine's Riots

Wil Sands has been embedded with the protestors since the outbreak of violence on Friday

If you haven't been following the riots in Ukraine, now is the time to start. Opposition leaders rejected President Yanukovych's concession offer Saturday, and are now calling for nothing short of his resignation. In the streets, protesters are hurling Molotov cocktails and seeking cover from rubber bullets. No one is backing down. Since the outbreak of the violence on Friday, photographer and journalist Wil Sands has been embedded with the protestors. Today, he sent us these exclusive, behind-the-lines images depicting the dramatic situation that's unfolding. -- JAMES JOINER
